"We got outside and, within two minutes, the fire brigade turned up. There are more than 100 people in the building. I do feel a bit shaken up."

The fire service said that crews from London Road and Carlton were called at 12.45pm. Firefighters wearing breathing apparatus used a main jet to tackle the fire. The incident had been dealt with by 1.25pm.

A spokesman said: "It is believed that the fire was started by a fault in a hair dryer resting on a pile of towels, plugged into a live electrical socket.

"No-one was injured but it does serve as a reminder that it is best to unplug electrical appliances or turn them off at the socket when they are not in use.

"When it comes to electrical items and appliances, always ensure that you do not leave things on charge overnight beyond the recommended charging time and keep electrical items away from flammable materials."
